Mous case!

In their advertising, they throw iphones in to the air, landing on concrete and no damage! The cases use some came of impact absorbing insert around the inner edge of the case. The case doesn't actively protect the screen, although there is a lip that prevent the screen hitting a flat surface directly, if it lands face down.
I've been using their Clarity case for a year now and dropped my 11 Pro Max a few times without damage. Not cheap mind...
